I think you should just use the amp as you would normally do and let it break in on its own. It is not like it will sound horrible in the process, it just may, perhaps, not b at its best.
My tube gear sounds quite decent after five to ten minutes of warm up. Tube gear gets up to song much faster than solid state stuff after being turned on, but, the downside is that it cannot be left on all of the time like most solid state gear.
It does NOT make sense to leave tube gear on for extended periods when you are not listening to the system. Tube life is limited by the hours of the gear being on. Tubes are NOT like incandescent lightbulbs and do not suffer, to the same extent, from the thermal shock of being turned on (particularly if the amp uses tube rectification and/or soft-start circuitry). But, once you turn a tube amp off, wait at least a few minutes before turning it back on; some amps don't like being short-cycled and may make loud noises if short-cycled.
Of course the particular gear matters, but, in my setup, I have not had ANY kind of service issue, including tubes going bad, in well over ten years of operation of my current gear (tube linestage, tube amp and tube phono preamp); the same cannot be said of my music server.
